 from all other Langurs. For the present species, Gray chose the 

 term Lasiopyga, proposed by Illiger in 1811 for nictitans and

 Geoffroy in 1812, who selected nem^us for the type of his genus 

 Pygathrix. Gray knew this for he cites Pygathrix, but he did 

 not heed the fact that the two species concerned were of different
